NAME Lingua::JA::Numbers - Converts numeric values into their Japanese string equivalents and vice versa VERSION $Revision: 0.3 $ $Date: 2005/08/18 07:16:13 $ SYNOPSIS use Lingua::JA::Numbers; # OO Style my $ja = Lingua::JA::Numbers->new(1234567890, {style=>'romaji'}); # JuuNiOkuSanzenYonHyakuGoJuuRokuManNanaSenHappyakuKyuuJuu # $ja->get_string is implictly called print "$ja\n"; print $ja+0, "\n"; # 1234567890 # $ja->number is implicitly called. # 1234567890 # Functional Style my $str = ja2num(1234567890, {style=>'romaji'}); print "$str\n"; # JuuNiOkuSanzenYonHyakuGoJuuRokuManNanaSenHappyakuKyuuJuu print num2ja($str), "\n"; # 1234567890 INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES This module requires perl 5.8.1 or better. It also uses bignum internally (that comes with perl core). DESCRIPTION This module converts Japanese text in UTF-8 (or romaji in ascii) to number, AND vice versa. Though this pod is in English and all examples are in romaji to make happy, this module does accept Japanese in UTF-8. Try the code below to see it. perl -MLingua::JA::Numbers \ -e '$y="\x{4e8c}\x{5343}\x{4e94}"; printf "(C) %d Dan Kogai\n", ja2num($y)' CAVEAT DO NOT BE CONFUSED WITH Lingua::JA::Number by Mike Schilli. This module is far more comprehensive. As of 0.03, it even does its to_string() upon request. METHODS This module supports the following methods. They are compliant with Lingua::En::Numbers and others. ->new($str [, {key=>var ...} ]) Constructs an object via $str. String can either be number or a string in Japanese that represents a number. Optionally take options. See "Functions" for options. ->parse($str, [, {key=>var ...} ]) Parses $str. ->opt(key => var) Changes internal options. ->get_string =item ->stringify =item ->as_string Stringifies the object accordingly to the options. The object auto-stringifies via overload so you don't usally need this. ->as_number =item ->numify Numifies the object. The object auto-numifies via overload so you don't usally need this. Functions This module supports the funcitons below; num2ja($num, [{key => value ... }]); =item number_to_ja() Converts the number to Japanese accordingly to the options. "number_to_ja()" is just an alias to "num2ja()". # \x{767e}\x{4e8c}\x{5341}\x{4e09} num2ja(123) # HyakuNijuuSan num2ja(123, {style=>"romaji"}) This function supports the options as follows; style => (kanji|romaji|hiragana|katakana) Sets which style (well, script but the word "script" is confusing). You can choose "kanji" (default), romaji, hiragana and katakana. daiji => (0|1|2) When 1, *daiji* is used. When 2 or larger, even those that are not represented as daiji will be in daiji. See for details. When this option is set to non-zero, "style" is ignored (kanji). p_one Forciblly prefix one even when not needed. print num2ja(1110, {style=>"romaji"}), "\n"; # SenHyakuJuu print num2ja(1110, {style=>"romaji", p_one=>1}), "\n"; # IchiSenIchiHyakuIchiJuu fixed4 Just stack numbers for thousands. print num2ja(2005, {style=>"romaji"}), "\n"; NiSenGo print num2ja(2005, {style=>"romaji", fixed4=>1}), "\n"; NiZeroZeroGo with_arabic Like "fixed4" but stack these numbers with arabic. print num2ja(20050831, {style=>"romaji"}), "\n"; # NiSenGoManHappyakuSanJuuIchi print num2ja(20050831, {style=>"romaji" with_arabic=>1}), "\n"; # 2005Man0831 manman Depreciated. When set to non-zero, it 8-digit (4x2) denomination for 'Goku' (10**48) and above. print num2ja(10**60, {style=>"romaji"}), "\n"; # IchiAsougi print num2ja(10**60, {style=>"romaji" manman=>1}), "\n"; # IchiManKougasha ja2num($str, [{key => value ... }]); =item ja_to_number() Converts Japanese number to number. Unlike "num2ja()", its counterpart, it supports only one option, "manman =" (0|1)> which toggles 8-digit denomination. It is pretty liberal on what it takes. For instance they all return 20050831. ja2num("NisenGoManHappyakuSanjuIchi") ja2num("NiZeroZeroGoZeroHachiSanIchi") ja2num("2005Man0831") ja2num() hacks ja2num() acts like a calculator -- the easiest way to support scientific notation was just that. Try ja2num("6.0225Kakeru10No23Jou") to_string() of Lingua::JA::Number Though not exported by default, This module comes with to_string() that is (upper-)compatibile with Lingua::JA::Number. my @words = Lingua::JA::Numbers::to_string(1234); print join('-', @words), "\n"; # "sen-ni-hyaku-san-ju-yon" EXPORT ja2num(), num2ja(), num2ja_ordinal(), ja_to_number(), number_to_ja(), number_to_ja_ordinal() BUGS bignum vs. Lingua::JA::Numbers Because of overload, The OO approach does not go well with bignum, despite the fact this module uses it internally Jo, or 10**24 The chacracter Jo (U+25771) which represents ten to twenty-four does not have a code point in BMP so it is represented in two letters that look like one (U+79be U+x4e88) SEE ALSO Lingua::En::Numbers Lingua::En::Number AUTHOR Dan Kogai, COPYRIGHT AND LICENSE Copyright (C) 2005 by Dan Kogai This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.8.7 or, at your option, any later version of Perl 5 you may have available.
